We investigated a highly active hydrogen production system by decomposition of water through the redox reaction of metal oxide at 623 K in an electric field (EF). Although Ce0.67Cr0.33O2 oxide showed high activity in the EF for oxygen release with the formation of lattice oxygen defects, it showed no hydrogen production activity by the regeneration of lattice oxygen defects with water. However, addition of Pd into the Ce0.67Cr0.33O2 structure promoted the hydrogen formation rate while maintaining its oxygen release activity. Results of optimization of the doping Pd amount demonstrated that 5 mol% Pd-doped oxide (Ce0.62Cr0.33Pd0.05O2) had the highest oxygen release rate and hydrogen formation rate. Doped Pd contributes to lattice strain induction and thereby increases the reaction rates.
